Kegel Exercise Balls are made of silicone which is 100% waterproof. According
to the kegel exercise theory, we designed these exercise courses especially to help those who have a loose vagina after giving birth. A set of Lena balls have three gradual increased weights
for different exercise needs. Effective kegel exercise helps to strengthen woman’s PC muscle,
improving health while bringing sexual benefits and satisfaction. For daily exercise or postpartum recovery, LENA balls are the perfect choice for you.
Inside of every Lena exercise balls, there’s a built-in moving metal ball. As you walk, run or
swim, the metal ball will collide with the inner surface, because of gravity the Lena balls tends
to slip out of your body, but the subtle vibration stimulates your PC muscle to shrink and stop
the ball from slipping out. The vibration may be subtle, but the repetitive shrinking will help
strengthen your PC muscle through your every movement.
